The Virtual Learning Environment Early Warning Base On Course Information

During the implementing the information of college curriculum, there is a low utilization of virtual learning environments(VLE) according to the teaching practice and literature research, that will not only restrict the process of information while continuing blind promotion and development of digital learning resources, but also result in idle learning resources, duplication of development and other issues. For this universal phenomenon, this paper completed course information technology in the leaning process early warning study on the virtual learning platform, we can monitored and tracked VLE behavior data to find the early warning information in the VLE process.According to VLE learning process the paper use the software engineering science method, first the feasibility analysis, needs analysis, system design and implementation system test, and then used the education scientific research method to carry on the early warning analysis, including of questionnaire index, design, statistics, analysis of qualitative and quantitative.The mainly content as the shown below in several aspects:The first, the system analysis design and implementation, by the using of large amounts of data generated by the students in WAMP platform, before the learning stage the different warning objects, for example registration, login, online elective, have been analyzed as to research basic information literacy of students, after entering the virtual learning platform the courseware, exercises, job, forum etc., have been excavated to study early warning platform utilization, finally the statistical data results of these two stages will be issued a warning information visualization graphics and will find the use of virtual learning platform visually; after learning students evaluate virtual learning platform satisfaction and the results have been analyzed and warning, the warning process innovation determined the warning index system according to the characteristics of virtual learning platform by the methods of education science research, the index system is the one level that information literacy, participation and satisfaction and ten second level indexes for complete the questionnaire making, and then the main use of mobile terminal software will complete the questionnaire, finishing survey produced a scientific index system, based on the use of HTML5, Android, PHP and MYSQL, warning title release, student warning data collection, choosing mean concentration and the frequency statistics and these visual warning messages will be realized.The second, the paper used the black box test to complete system function, including “registered”, “login”, “selection course”, “work”, “discussion” and so on; and others function including the warning system in the mobile it is item modify, answer the questions,the answer statistics and analysis and so on.The third, system apply, after the information of C++ courses from a Heilongjiang university, the VLE platform data during pre-studying, studying and after studying have been analyzed, suggestion is given on the dynamic module based on virtual learning platform, according to the environmental factors, personal factors and course information resource factors is discussed. It is important that strengthen student information literacy, construction the learning resources with good navigation and school based network design and popularity.
